Kabuto king effect
When someone or a gang of f***ing jerks buys everything cheap before anyone else even thinks about it, then when everyone wants it, there’s nothing left and the price goes up like a f***ing curse.
A kid buys all the cheapest candy in the store before the whole class starts craving it.
A group of people grabs all the cheapest drinks before the event even starts.
A rich dude buys up every single cheapest concert ticket before the band becomes a thing.
